　なお、サーボモータは、電気モータと、電気モータの回転子の回転角を検出するエンコーダと、電気モータの電流値を検出する電流センサとを備えている。サーボモータは、サーボアンプ９１から出力される電流によって、電気モータを動作させ、エンコーダ及び電流センサの検出値をサーボアンプ９１に出力する。サーボアンプ９１は、サーボモータからフィードバックされたエンコーダの検出値に基づき、当該サーボモータの回転子の回転量及び回転速度等を検出し、回転子の回転量及び回転速度並びに電流センサの電流値等の検出結果を用いて当該サーボモータの回転開始、回転停止、回転速度及び回転トルクを制御する。これにより、サーボアンプ９１は、サーボモータを任意の回転位置で停止させることができ、任意の回転速度で回転させることができ、任意の回転トルクで動作させることができる。よって、サーボモータによって駆動されるロボットの各部は多様に且つ緻密に動作することができる。 The servomotor is equipped with an electric motor, an encoder that detects the rotation angle of the rotor of the electric motor, and a current sensor that detects the current value of the electric motor. The servomotor operates the electric motor by the current output from the servo amplifier 91, and outputs the detected values of the encoder and the current sensor to the servo amplifier 91. The servo amplifier 91 detects the rotation amount and rotation speed of the rotor of the servomotor based on the detection value of the encoder fed back from the servomotor, and the rotation amount and rotation speed of the rotor and the current value of the current sensor and the like. The rotation start, rotation stop, rotation speed, and rotation torque of the servomotor are controlled by using the detection result of. As a result, the servo amplifier 91 can stop the servomotor at an arbitrary rotation position, rotate it at an arbitrary rotation speed, and operate it at an arbitrary rotation torque. Therefore, each part of the robot driven by the servomotor can operate in various and precise manners.
　第二回路１００は、電気回路であり、ブレーカ１０１及び変圧器１０２等を含む。ブレーカ１０１は第三室２０３ａに配置され、変圧器１０２は第三室２０３ｂに配置されている。ブレーカ１０１と変圧器１０２とは電気的に接続され、ブレーカ１０１は作動することで変圧器１０２への供給電流を遮断する。変圧器１０２は、ブレーカ１０１を介して外部電源から供給された電力を変圧し第一回路９０のパワーユニット９２に供給する。変圧器１０２は通電時に発熱する。なお、第三室２０３ｂには、変圧器１０２に加えて又は変圧器１０２の代わりに、他の電気回路等が配置されてもよい。 The second circuit 100 is an electric circuit and includes a breaker 101, a transformer 102, and the like. The breaker 101 is arranged in the third chamber 203a, and the transformer 102 is arranged in the third chamber 203b. The breaker 101 and the transformer 102 are electrically connected, and the breaker 101 operates to cut off the supply current to the transformer 102. The transformer 102 transforms the electric power supplied from the external power source via the breaker 101 and supplies it to the power unit 92 of the first circuit 90. The transformer 102 generates heat when energized. In addition, in addition to the transformer 102 or in place of the transformer 102, another electric circuit or the like may be arranged in the third chamber 203b.
　ヒートシンク１１１～１１３は、第一隔壁２６に配置され、ヒートシンク１１４は、第二隔壁２７に配置されている。ヒートシンク１１１～１１４は、熱伝導性の高い材料で構成されている。例えば、ヒートシンク１１１～１１４は、アルミニウム、鉄、銅等の熱伝導性の高い金属で構成されてもよい。 The heat sinks 111 to 113 are arranged on the first partition wall 26, and the heat sink 114 is arranged on the second partition wall 27. The heat sinks 111 to 114 are made of a material having high thermal conductivity. For example, the heat sinks 111 to 114 may be made of a metal having high thermal conductivity such as aluminum, iron, and copper.
　図６は、図５のロボット用制御装置１のＶＩ－ＶＩ線に沿った断面図である。図６に示すように、ヒートシンク１１１は、支持板１１５を介して第一隔壁２６に配置されている。ヒートシンク１１１は支持板１１５に取り付けられている。支持板１１５は第一隔壁２６に取り付けられ、第一隔壁２６に形成された図示しない開口を塞ぐ。ヒートシンク１１１は、第一室２０１及び第二室２０２に露出している。第一室２０１において、ヒートシンク１１１は、第一回路９０のサーボアンプ９１の熱が伝達されるように構成されている。例えば、ヒートシンク１１１は、図示しない薄厚の絶縁部材を介してサーボアンプ９１と隣接して配置される。 FIG. 6 is a cross-sectional view of the robot control device 1 of FIG. 5 along the VI-VI line. As shown in FIG. 6, the heat sink 111 is arranged on the first partition wall 26 via the support plate 115. The heat sink 111 is attached to the support plate 115. The support plate 115 is attached to the first partition wall 26 and closes an opening (not shown) formed in the first partition wall 26. The heat sink 111 is exposed in the first chamber 201 and the second chamber 202. In the first chamber 201, the heat sink 111 is configured to transfer the heat of the servo amplifier 91 of the first circuit 90. For example, the heat sink 111 is arranged adjacent to the servo amplifier 91 via a thin insulating member (not shown).
　また、ヒートシンク１１１は、第二室２０２に突出する複数の放熱板を一体的に含み、複数の放熱板を介して第二室２０２内の空気と接触し熱交換する。これにより、ヒートシンク１１１は、サーボアンプ９１の熱を第二室２０２に放熱することができる。そして、ヒートシンク１１１は、複数の放熱板によって、熱交換を行うための面積を増大することができる。なお、支持板１１５は、ヒートシンク１１１と同様に、熱伝導性の高い材料で構成されていてもよい。さらに、支持板１１５とヒートシンク１１１とは、同じ材料で構成され一体化されていてもよい。これにより、サーボアンプ９１の熱を第二室２０２に放熱するための面積を増大させることができる。さらに、部品点数の低減が可能である。 Further, the heat sink 111 integrally includes a plurality of heat radiating plates protruding from the second chamber 202, and contacts the air in the second chamber 202 through the plurality of heat radiating plates to exchange heat. As a result, the heat sink 111 can dissipate the heat of the servo amplifier 91 to the second chamber 202. The area of the heat sink 111 for heat exchange can be increased by the plurality of heat radiating plates. The support plate 115 may be made of a material having high thermal conductivity, similarly to the heat sink 111. Further, the support plate 115 and the heat sink 111 may be made of the same material and integrated. As a result, the area for dissipating the heat of the servo amplifier 91 to the second chamber 202 can be increased. Furthermore, the number of parts can be reduced.
　ヒートシンク１１２及び１１３は、ヒートシンク１１１よりも上方において、支持板１１６を介して第一隔壁２６に配置されている。つまり、ヒートシンク１１２及び１１３と、ヒートシンク１１１とは、第一扉開口３０ａ及び３０ｂから第二開口２４ａ～２４ｄに向かう方向であり且つ送風装置４０が発生する気流の方向である気流方向に対して交差する方向に、配列される。ヒートシンク１１２及び１１３は支持板１１６に取り付けられている。支持板１１６は第一隔壁２６に取り付けられ、第一隔壁２６に形成された図示しない開口を塞ぐ。ヒートシンク１１２及び１１３は、第一室２０１及び第二室２０２に露出している。第一室２０１において、ヒートシンク１１２及び１１３は、第一回路９０のパワーユニット９２の熱が伝達されるように構成されている。例えば、ヒートシンク１１２及び１１３は、図示しない薄厚の絶縁部材を介してパワーユニット９２と隣接して配置される。 The heat sinks 112 and 113 are arranged on the first partition wall 26 via the support plate 116 above the heat sink 111. That is, the heat sinks 112 and 113 and the heat sink 111 intersect with respect to the airflow direction which is the direction from the first door openings 30a and 30b toward the second openings 24a to 24d and the direction of the airflow generated by the blower 40. It is arranged in the direction of the door. The heat sinks 112 and 113 are attached to the support plate 116. The support plate 116 is attached to the first partition wall 26 and closes an opening (not shown) formed in the first partition wall 26. The heat sinks 112 and 113 are exposed in the first chamber 201 and the second chamber 202. In the first chamber 201, the heat sinks 112 and 113 are configured to transfer the heat of the power unit 92 of the first circuit 90. For example, the heat sinks 112 and 113 are arranged adjacent to the power unit 92 via a thin insulating member (not shown).
　また、ヒートシンク１１２及び１１３はそれぞれ、第二室２０２に突出する複数の放熱板を一体的に含み、複数の放熱板を介して第二室２０２内の空気と接触し熱交換する。これにより、ヒートシンク１１２及び１１３は、パワーユニット９２の熱を第二室２０２に放熱することができる。そして、ヒートシンク１１２及び１１３はそれぞれ、複数の放熱板によって、熱交換を行うための面積を増大することができる。なお、支持板１１６は、熱伝導性の高い材料で構成されていてもよい。さらに、支持板１１６とヒートシンク１１２及び１１３とは、同じ材料で構成され一体化されていてもよい。これにより、パワーユニット９２の熱を第二室２０２に放熱するための面積を増大させることができる。さらに、部品点数の低減が可能である。 Further, each of the heat sinks 112 and 113 integrally includes a plurality of heat radiating plates protruding into the second chamber 202, and contacts the air in the second chamber 202 through the plurality of heat radiating plates to exchange heat. As a result, the heat sinks 112 and 113 can dissipate the heat of the power unit 92 to the second chamber 202. The areas of the heat sinks 112 and 113 for heat exchange can be increased by a plurality of heat radiating plates, respectively. The support plate 116 may be made of a material having high thermal conductivity. Further, the support plate 116 and the heat sinks 112 and 113 may be made of the same material and integrated. As a result, the area for dissipating the heat of the power unit 92 to the second chamber 202 can be increased. Furthermore, the number of parts can be reduced.
　図５に戻り、ヒートシンク１１４は、第二隔壁２７に配置されている。ヒートシンク１１４は、第二室２０２に対して、ヒートシンク１１１～１１３と反対側に配置されている。ヒートシンク１１４は、ヒートシンク１１１～１１３と同様に、第二隔壁２７に形成された図示しない開口を塞ぐ支持板（図示せず）を介して第二隔壁２７に配置されてもよい。ヒートシンク１１４は、第二室２０２及び第三室２０３ｂに露出している。第三室２０３ｂにおいて、ヒートシンク１１４は、変圧器１０２の熱が伝達されるように構成されている。例えば、ヒートシンク１１４は、図示しない薄厚の絶縁部材を介して変圧器１０２と隣接して配置される。 Returning to FIG. 5, the heat sink 114 is arranged on the second partition wall 27. The heat sink 114 is arranged on the side opposite to the heat sinks 111 to 113 with respect to the second chamber 202. Similar to the heat sinks 111 to 113, the heat sink 114 may be arranged on the second partition wall 27 via a support plate (not shown) that closes an opening (not shown) formed in the second partition wall 27. The heat sink 114 is exposed in the second chamber 202 and the third chamber 203b. In the third chamber 203b, the heat sink 114 is configured to transfer the heat of the transformer 102. For example, the heat sink 114 is arranged adjacent to the transformer 102 via a thin insulating member (not shown).
　また、ヒートシンク１１４は、第二室２０２に突出する複数の放熱板を一体的に含み、複数の放熱板を介して第二室２０２内の空気と接触し熱交換する。これにより、ヒートシンク１１４は、変圧器１０２の熱を第二室２０２に放熱することができる。そして、ヒートシンク１１４は、複数の放熱板によって、熱交換を行うための面積を増大することができる。なお、ヒートシンク１１４を支持する支持板（図示せず）が、熱伝導性の高い材料で構成されていてもよく、さらに、ヒートシンク１１４と同じ材料で構成され一体化されていてもよい。これにより、変圧器１０２の熱を第二室２０２に放熱するための面積を増大させることができる。さらに、部品点数の低減が可能である。 Further, the heat sink 114 integrally includes a plurality of heat radiating plates protruding from the second chamber 202, and contacts the air in the second chamber 202 through the plurality of heat radiating plates to exchange heat. As a result, the heat sink 114 can dissipate the heat of the transformer 102 to the second chamber 202. The area of the heat sink 114 for heat exchange can be increased by the plurality of heat radiating plates. The support plate (not shown) that supports the heat sink 114 may be made of a material having high thermal conductivity, or may be made of the same material as the heat sink 114 and integrated. As a result, the area for dissipating the heat of the transformer 102 to the second chamber 202 can be increased. Furthermore, the number of parts can be reduced.
　また、制御装置１は、第二隔壁２７に配置された抵抗体１３１を備えてもよい。抵抗体１３１は第二室２０２に露出している。抵抗体１３１は通電されることで発熱する電気抵抗体である。抵抗体１３１は、第一回路９０と電気的に接続され、第一回路９０からの余剰電力を消費するように構成されている。抵抗体１３１は、発熱することで供給された電力を消費する。抵抗体１３１は、第二室２０２内の空気と接触し熱交換することで発生した熱を放熱する。例えば、ロボットのサーボモータは回生電力を発生する場合があり、この回生電力が第一回路９０に供給され、余剰の電力となり得る。第一回路９０は、当該回路を保護するために余剰の電力を抵抗体１３１に供給する。 Further, the control device 1 may include a resistor 131 arranged on the second partition wall 27. The resistor 131 is exposed in the second chamber 202. The resistor 131 is an electric resistor that generates heat when energized. The resistor 131 is electrically connected to the first circuit 90 and is configured to consume the surplus power from the first circuit 90. The resistor 131 consumes the supplied electric power by generating heat. The resistor 131 dissipates heat generated by contacting with the air in the second chamber 202 and exchanging heat. For example, the servomotor of the robot may generate regenerative power, and this regenerative power may be supplied to the first circuit 90 to become surplus power. The first circuit 90 supplies the resistor 131 with excess power to protect the circuit.
　＜制御装置の動作＞
　実施の形態に係る制御装置１の動作を説明する。図１及び図２に示すように、ロボット（図示せず）を制御する使用時等を含む通常時、制御装置１の筐体１０の扉３０は閉じられている。このとき、筐体１０の第一室２０１並びに第三室２０３ａ及び２０３ｂは閉塞されている。第二室２０２は、第一扉開口３０ａ及び３０ｂ、第一開口２０ａ、並びに、第二開口２４ａ～２４ｄを介して、筐体１０の外部に開放されている。 <Operation of control device>
The operation of the control device 1 according to the embodiment will be described. As shown in FIGS. 1 and 2, the door 30 of the housing 10 of the control device 1 is closed during normal times including use for controlling a robot (not shown). At this time, the first chamber 201 and the third chambers 203a and 203b of the housing 10 are closed. The second chamber 202 is opened to the outside of the housing 10 through the first door openings 30a and 30b, the first opening 20a, and the second openings 24a to 24d.
　図５及び図６に示すように、制御装置１の使用時、制御装置１は通電され、それにより、第一回路９０及び第二回路１００は通電される。第一回路９０は、送風装置４０を稼働させる。さらに、第一回路９０は、サーボアンプ９１及びパワーユニット９２を駆動し、制御装置１と電気的に接続されたロボット（図示せず）を動作させる。具体的には、第一回路９０は、サーボモータを駆動することでロボットのアームの関節及びエンドエフェクタ（図示せず）等を動作させる。 As shown in FIGS. 5 and 6, when the control device 1 is used, the control device 1 is energized, whereby the first circuit 90 and the second circuit 100 are energized. The first circuit 90 operates the blower 40. Further, the first circuit 90 drives the servo amplifier 91 and the power unit 92 to operate a robot (not shown) electrically connected to the control device 1. Specifically, the first circuit 90 operates a robot arm joint, an end effector (not shown), and the like by driving a servomotor.
　送風装置４０のファン４１は、一方向に回転駆動することにより、筐体１０の前方から後方に向かう気流を強制的に発生させる。つまり、ファン４１は、第一扉開口３０ａ及び３０ｂ並びに第一開口２０ａを通って第二室２０２に流入し且つ第二開口２４ａ～２４ｄを通って第二室２０２から流出する気流を発生させる。よって、第二室２０２は、第一扉開口３０ａ及び３０ｂから第二開口２４ａ～２４ｄに向かう直線状の気体の流路を構成する。なお、ファン４１は、上記の一方向と反対方向に回転駆動されてもよい。この場合、第二室２０２内では、第二開口２４ａ～２４ｄから第一扉開口３０ａ及び３０ｂに向かう気流が生成される。 The fan 41 of the blower device 40 is rotationally driven in one direction to forcibly generate an air flow from the front to the rear of the housing 10. That is, the fan 41 generates an air flow that flows into the second chamber 202 through the first door openings 30a and 30b and the first opening 20a and flows out from the second chamber 202 through the second openings 24a to 24d. Therefore, the second chamber 202 constitutes a linear gas flow path from the first door openings 30a and 30b to the second openings 24a to 24d. The fan 41 may be rotationally driven in a direction opposite to the above one direction. In this case, in the second chamber 202, an air flow is generated from the second openings 24a to 24d toward the first door openings 30a and 30b.
　外気は、ファン４１によって第二室２０２内に強制的に導入された後、強制的に排出される。導入された外気は、ヒートシンク１１１～１１４と接触し熱交換することで吸熱する。これにより、第一回路９０のサーボアンプ９１及びパワーユニット９２の熱は、ヒートシンク１１１～１１３を介して外気に吸熱される。さらに、第二回路１００の変圧器１０２の熱は、ヒートシンク１１４を介して外気に吸熱される。また、外気は、抵抗体１３１と接触し熱交換することで吸熱する。 The outside air is forcibly introduced into the second chamber 202 by the fan 41 and then forcibly discharged. The introduced outside air absorbs heat by contacting the heat sinks 111 to 114 and exchanging heat. As a result, the heat of the servo amplifier 91 and the power unit 92 of the first circuit 90 is endothermic to the outside air via the heat sinks 111 to 113. Further, the heat of the transformer 102 of the second circuit 100 is endothermic to the outside air through the heat sink 114. Further, the outside air absorbs heat by contacting with the resistor 131 and exchanging heat.
　サーボアンプ９１に対して吸熱するヒートシンク１１１と、パワーユニット９２に対して吸熱するヒートシンク１１２及び１１３とは、筐体１０の上下方向に分かれて配置されている。ヒートシンク１１１と、ヒートシンク１１２及び１１３とは、送風装置４０によって生成される外気の流れの上流又は下流の位置関係で配列されず、外気の流れの方向と交差する方向に配列されている。ヒートシンク１１１が熱交換する外気は、ヒートシンク１１２又は１１３との熱交換後の外気ではなく、筐体１０の外部から導入された新鮮な外気である。ヒートシンク１１２及び１１３が熱交換する外気は、ヒートシンク１１１との熱交換後の外気ではなく、筐体１０の外部から導入された新鮮な外気である。これにより、ヒートシンク１１１～１１３での高い効率での熱交換が可能である。なお、図６では、ヒートシンク１１３は、ヒートシンク１１２に対して、第二室２０２内の外気の流れの下流に位置するが、上下方向にずらして配置されてもよい。これにより、ヒートシンク１１３には、より新鮮な外気が導入される。 The heat sink 111 that absorbs heat from the servo amplifier 91 and the heat sinks 112 and 113 that absorb heat from the power unit 92 are arranged separately in the vertical direction of the housing 10. The heat sink 111 and the heat sinks 112 and 113 are not arranged in a positional relationship upstream or downstream of the flow of outside air generated by the blower 40, but are arranged in a direction intersecting the direction of the flow of outside air. The outside air that the heat sink 111 exchanges heat with is not the outside air after heat exchange with the heat sink 112 or 113, but the fresh outside air introduced from the outside of the housing 10. The outside air that the heat sinks 112 and 113 exchange heat with is not the outside air after the heat exchange with the heat sink 111, but the fresh outside air introduced from the outside of the housing 10. As a result, heat exchange between the heat sinks 111 to 113 can be performed with high efficiency. In FIG. 6, the heat sink 113 is located downstream of the flow of outside air in the second chamber 202 with respect to the heat sink 112, but may be arranged so as to be displaced in the vertical direction. As a result, fresher outside air is introduced into the heat sink 113.
　また、ヒートシンク１１４は、第二室２０２に関して、筐体１０の左右方向、つまり、外気の流れに直交する方向で、ヒートシンク１１１～１１３と反対側に配置されている。ヒートシンク１１４が熱交換する外気は、ヒートシンク１１１～１１３の熱交換による影響が低い外気である。これにより、ヒートシンク１１４での高い効率での熱交換が可能である。 Further, the heat sink 114 is arranged on the side opposite to the heat sinks 111 to 113 with respect to the second chamber 202 in the left-right direction of the housing 10, that is, in the direction orthogonal to the flow of the outside air. The outside air that the heat sink 114 exchanges heat with is the outside air that is less affected by the heat exchange of the heat sinks 111 to 113. As a result, heat exchange with high efficiency in the heat sink 114 is possible.
　また、第一室２０１並びに第三室２０３ａ及び２０３ｂは、第二室２０２から遮蔽されており、送風装置４０による外気の強制的な導入も受けない。このため、第一室２０１並びに第三室２０３ａ及び２０３ｂへの異物の侵入が抑えられる。 Further, the first chamber 201 and the third chambers 203a and 203b are shielded from the second chamber 202, and are not subject to the forced introduction of outside air by the blower 40. Therefore, the invasion of foreign matter into the first chamber 201 and the third chambers 203a and 203b is suppressed.
　また、外気の導出入部が筐体１０の前面の扉３０と背面の側壁２４とに限定される。さらに、扉３０に、保持部材３２、操作器コネクタ５０、操作パネル６０及びブレーカスイッチ１０１ａが配置され、側壁２４に、ロボットコネクタ８１が配置されている。このため、底壁２１、側壁２２及び２３、並びに頂壁２５に隣接して、筐体１０の周囲に、他の制御装置１等の他の装置の配置が可能である。例えば、複数の制御装置１が、上下方向及び左右方向に積み重ねられて配置されることが可能である。 Further, the outside air lead-in / entry portion is limited to the front door 30 and the back side wall 24 of the housing 10. Further, a holding member 32, an operator connector 50, an operation panel 60 and a breaker switch 101a are arranged on the door 30, and a robot connector 81 is arranged on the side wall 24. Therefore, other devices such as another control device 1 can be arranged around the housing 10 adjacent to the bottom wall 21, the side walls 22 and 23, and the top wall 25. For example, a plurality of control devices 1 can be stacked and arranged in the vertical direction and the horizontal direction.
　また、図３及び図５に示すように、制御装置１のメンテナンス時等を含む非通常時、筐体１０の扉３０が開放される。１つの扉３０を開放するのみで、第一開口２０ａを通じて、第一室２０１、第二室２０２並びに第三室２０３ａ及び２０３ｂへアクセスできる。例えば、第一回路９０、送風装置４０、及びブレーカ１０１の点検、修理及び交換が可能である。さらに、第三隔壁２８を取り外すことによって、第三室２０３ｂ内の点検等が可能である。 Further, as shown in FIGS. 3 and 5, the door 30 of the housing 10 is opened during an abnormal time including maintenance of the control device 1. By opening only one door 30, the first room 201, the second room 202, and the third room 203a and 203b can be accessed through the first opening 20a. For example, the first circuit 90, the blower 40, and the breaker 101 can be inspected, repaired, and replaced. Further, by removing the third partition wall 28, it is possible to inspect the inside of the third chamber 203b.

According to the above configuration, the second chamber 202 having the first opening 20a or the second openings 24a to 24d as the introduction port and the outlet port can form a linear air flow path inside the second chamber 202. Therefore, it becomes possible to smooth the flow of air in the second chamber 202, and the heat exchange efficiency by air is improved. When the first opening 20a is located at the front of the housing 10, the second openings 24a to 24d are located at the rear of the housing 10. Therefore, it is possible to arrange other objects laterally and vertically of the housing 10. For example, the housings 10 can be stacked vertically and horizontally.

Therefore, the heat exchange efficiency can be improved.
　また、実施の形態において、第一回路９０は、サーボアンプ９１及びパワーユニット９２を含み、少なくとも２つの第一ヒートシンク１１１～１１３が、サーボアンプ９１及びパワーユニット９２の熱が伝達可能に配置されてもよい。さらに、サーボアンプ９１の熱が伝達可能な第一ヒートシンク１１１と、パワーユニット９２の熱が伝達可能な第一ヒートシンク１１２及び１１３とは、送風装置４０によって第二室２０２に生成される空気の流れの方向と交差する方向に配列されてもよい。上記構成によると、第一ヒートシンク１１１と熱交換した後の空気が、第一ヒートシンク１１２及び１１３と熱交換することが抑制される。第一ヒートシンク１１２及び１１３と熱交換した後の空気が、第一ヒートシンク１１１と熱交換することが抑制される。よって、第一ヒートシンク１１１と、第一ヒートシンク１１２及び１１３とはいずれも、新鮮な空気と熱交換することができる。従って、熱交換効率の向上が可能になる。 Further, in the embodiment, the first circuit 90 includes the servo amplifier 91 and the power unit 92, and at least two first heat sinks 111 to 113 may be arranged so that the heat of the servo amplifier 91 and the power unit 92 can be transferred. .. Further, the first heat sink 111 capable of transferring the heat of the servo amplifier 91 and the first heat sinks 112 and 113 capable of transferring the heat of the power unit 92 are the flow of air generated in the second chamber 202 by the blower 40. It may be arranged in a direction intersecting the direction. According to the above configuration, the air after heat exchange with the first heat sink 111 is suppressed from heat exchange with the first heat sinks 112 and 113. The air after heat exchange with the first heat sinks 112 and 113 is suppressed from heat exchange with the first heat sink 111. Therefore, both the first heat sink 111 and the first heat sinks 112 and 113 can exchange heat with fresh air. Therefore, the heat exchange efficiency can be improved.
　また、実施の形態において、制御装置１は、本体２０が有する第三室２０３ａ及び２０３ｂに第二回路１００を備え、第三室２０３ａ及び２０３ｂは、第二隔壁２７を介して第二室２０２と隣接してもよい。上記構成によると、第二隔壁２７を介して、第二室２０２内の空気と、第三室２０３ａ及び２０３ｂ内の空気及び第二回路１００との熱交換が可能であり、第二回路１００の熱が第二室２０２へ放出される。よって、１つの第二室２０２を用いて第一室２０１並びに第三室２０３ａ及び２０３ｂ内の熱の放出が可能である。従って、制御装置１の構造の簡略化が可能である。なお、第三室２０３ａ及び２０３ｂは、第二室２０２に関して第一室２０１と反対側に配置されてもよい。第一室２０１、第二室２０２、並びに、第三室２０３ａ及び２０３ｂが一列に並ぶため、筐体１０のコンパクト化が可能である。 Further, in the embodiment, the control device 1 includes the second circuit 100 in the third chambers 203a and 203b of the main body 20, and the third chambers 203a and 203b are connected to the second chamber 202 via the second partition wall 27.
